Introduction¶
Project Overview¶
This project focuses on analyzing patterns or trends in criminal acitivity data from 2021 to 2024 obtained from the Major Crime Indicators (MCI) dataset in Toronto. The objective is to make predictions on the future patterns of criminal activity based on the patterns present in the current data.
Tools & Technologies Used¶
Data Retrieval:
Requests (Python)for making API calls to retrieve the data for analysis and visualization purposes.
Data Manipulation:
Pandasfor majority of data cleaning, preprocessing, and manipulation steps.GeoPandasfor preprocessing and manipulating GeoJSON data.
Machine Learning:
Scikit-learnfor applying regression algorithms (e.g., Random Forest Regressor, Histogram-Based Gradient Boosting, etc.) and ensemble learning and optimization methods (e.g., Voting Regressor, ADA Boosting, Hyper-Parameter Tuning, etc.) to predict future crime trends.
Data Visualization:
Matplotlib and Seaborn (Python)for visualizing crime trends over time.Folium (Python)for visualizing geospatial data.
Data Sources¶
Toronto Police Service Major Crime Indicators (MCI) Data:
This dataset includes all Major Crime Indicators (MCI) occurrences by reported date and related offences since 2014. The Major Crime Indicators categories include Assault, Break and Enter, Auto Theft, Robbery and Theft Over (Excludes Sexual Violations).
This data is provided at the offence and/or victim level, therefore one occurrence number may have several rows of data associated to the various MCIs used to categorize the occurrence.
This data does not include occurrences that have been deemed unfounded. The definition of unfounded according to Statistics Canada is: “It has been determined through police investigation that the offence reported did not occur, nor was it attempted” (Statistics Canada, 2020).**
The location of crime occurrences have been deliberately offset to the nearest road intersection node to protect the privacy of parties involved in the occurrence...Due to the offset of occurrence location, the numbers by...Neighbourhood may not reflect the exact count of occurrences reported within these [neighbourhoods].

- Further information on the dataset available here.
- The data is accessed by an ArcGIS REST API.
Neighbourhoods Data:
- City-of-Toronto-designated social planning neighbourhood boundaries defined primarily to help City staff collect data, plan, analyze and forecast City services.
